IMPROVEMENT IN ADJUSTABLE TOPS.

Specification forming part of Letters Patent No. 162,797, dated May 4,1875; application filed November 21, 1874.

Similar letters of reference indicate corre-' sponding parts.

My invention relates to an improved device for adjusting the canopy ofchildrens and other carriages, in a simple, quick, and reliable manner,in any required position for shading against the sun, and otherpurposes.

The invention consists of a curved standard or arm, which is attached tothe body of the carriage and provided, at the upper end, with a pivotedpulley, operated by means of a turning spring-knob and connecting-cords.A canopy or parasol, with arc-shaped slidepiece, is adjusted by aclamping device to the pulley, and set to any inclination thereon.

A represents a curved supporting-standard or arm, which is of suitablestrength, and applied by fastening-screws to the body of a childs orother carriage. The upper end of the standard extends to a point nearlyvertical above the center of the body, and carries a pivoted pulley, B,to the under side of which is attached, by a suitable clampingarrangement, B, the arc-shaped arm C of a canopy,

parasol, or other protecting device, so thatthe same may be readilyadjusted on the pulley in horizontal or inclined position, as desired.The pulley is turned to either side, together with the canopy, by meansof cords D, which are applied at opposite sides of the circumference ofthe pulley, and passed through guide-eyes or staples a of the standardto a spring-knob, E, being attached to the pulley and knob in suchmanner that the unwinding of one cord, on the turning of the knob,produces the winding up of the other cord, and thereby the readyswinging around of the pulley and canopy in any desired position. Theknob or handleE turns on apivot or shaft attached at. some convenientheight to the standard A, and slides with such play along the same thata notched or recessed disk or ratchet-plate, d, at its lower side, maybe disengaged from a stationary tooth or pin, 61, of standard A,allowing the turning. of the knob to either side. A spiral spring, e, atthe end of the knob, carries the same back as soon as released,andsecures thereby the position of the knob, pulley, and canopy. Astop-pin, f, projects from the under side of the knob, and defines, byits contact with standard A, the extent of turning the knob in eitherdirection, so that the cords remain always stretched, and do not comeoff the knob.

The adjusting device forms a neat and convenient attachment to childsand other carriages, as the canopy may be set to any inclination anddirection, and produces thereby a complete and etficieut shade againstthe sun.

Having thus described myinven tion, I claim as new and desire to secureby Letters Patent 1. The canopy-adjusting device, composed of curvedsupporting standard with rotating end pulley, having adjustable canopyto be operated by spring-knob and connecting-cords, all combinedsubstantially as specified.

2. The combination of a rotating pulley, B, having clamping .device B,with arc-shaped slide-piece C, attached to canopy for setting the sameunder any inclination to the carriage-body, as specified.

3. The pivoted spring knob E, having ratchet base-plate d, and stop-pinf, combined with standard A and pin 61, for defining eX- tent of turningmotion of knob and securing its position when set, substantially asspecified.
